Maxfield is charged with two counts of vehicular homicide while driving under the influence of alcohol, two counts of vehicular homicide while driving recklessly and 10 other charges.

Authorities allege Maxfield sped away from officers, ran several red lights and slammed his speeding Honda Civic into a pickup at Fifth Street and North Avenue on Feb. 28, killing 21-year-old Shandi Boetel and her 6-month-old daughter, Natalia Casiano.

A search warrant affidavit in the case said a Mesa County Sheriff’s Department deputy estimated Maxfield’s Honda Civic was going 70 mph in a posted 35 mph area in downtown Grand Junction minutes before the crash.

The affidavit said Maxfield registered a blood-alcohol content of 0.21 percent just after the accident, nearly three times Colorado’s legal limit for driving a vehicle.

Shandi Boetel’s mother, Tammy Ulibarri, named Maxfield in a wrongful death lawsuit, filed June 8, seeking unspecified monetary damages for “loss of companionship,” among other claims.

Maxfield appeared free on bond Tuesday in District Judge Richard Gurley’s courtroom.
